Gold tip hunter 7595 will work for you in a 29.5" length A little stiff at 60 Lbs, but PERFECT at 70 Lbs
With 125 gn tips, and 3 4 3/4" vanes you'd be around 443 grains. 3 7/8" vanes would put you at around 422.
You could go longer with the arrow, and bring the spine for the 60 lbs closer to ideal. You would have to go a good deal longer to get out of the green (The archery program) for 70 lbs.
Those arrows are 8.9 grains per inch.
